現在已經實現的功能有：

1.用給定的字符填充源字符串的左邊以達到指定的長度

2.用給定的字符填充源字符串的右邊以達到指定的長度

3.轉半角的函數(DBC case)

4.轉全角的函數(SBC case)

5.漢字轉拼音縮寫

6.取單個字符的拼音聲母

等等

演示一下:漢字轉拼音縮寫

?我是那Windows窗體寫的

代碼:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace PyCodeDemo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void label1_Click(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.label1.Text = StringHelper.PYConvert(this.textBox1.Text.Trim(), true);
        }
    }
}
 

實現後的結果:
